Geomagnetic Motion Tracking Products

Any compass incorporated into a host system requires calibration so that the compass properly compensates for ferrous and magnetic components. If this is not done correctly, heading readings can be very inaccurate.

Designing Rugged, Standards-Based Embedded Solutions

It can be argued that small form factor design trends are paradoxical. As form factor size decreases, functionality requirements increase; as processing power requirements heighten, lower power consumption and thermal output is expected. Add to that the requirement for ruggedness to accommodate for the shock, vibration, humidity, and temperature extremes and variance inherent in mobile and outdoor applications, and designers are faced with a very complex soup.

Tips for Selecting or Designing a Membrane Switch

Membrane switches are known for standing up to tough environmental conditions. Flexible and durable, the membrane switch can be customized with embossing, backlighting, sealing, and electrostatic discharge (ESD) shielding. Membrane switches can be made with either tactile or non-tactile feedback and they can be integrated with LEDs and other components. To get the switch that works for your application, follow these simple guidelines.

Pursuing Agile Signals in a Crowded Spectral Environment

For the capable RF engineer, continuous- wave (CW) and predictably repeating signals are no great challenge. However, design and troubleshooting become difficult when dealing with agile signals, and the challenges grow when these signals exist in an environment densely populated with similarly agile signals. Examples include applications such as radar, electronic warfare, wireless connectivity, and wireless communications. Indeed, some engineering jobs must be performed where two or more of these technologies intersect — sometimes accidentally and sometimes deliberately.

Virtex-7 XMC and VPX Boards

4DSP LLC (Austin, TX) recently introduced the FM780 and VP780, two highly configurable modules with advanced digital signal processing (DSP) capabilities and multiple I/O options. The FM780 is XMC (VITA 42.3) compliant with a PCI Express Gen 2 interconnect while the VP780 is 3U VPX form factor (VITA 46) compliant. Both modules provide an FMC (FPGA Mezzanine Card, VITA 57) site and two 4DSP BLAST (Board Level Application Scalable Technology) locations that are closely coupled to the onboard Xilinx Virtex®-7 FPGA and 2GB of DDR3 SDRAM.

RF Transceiver Module

National Instruments (Austin, TX) has released the NI 5791 RF transceiver adapter module for NI FlexRIO, which is currently being used in 5G technologies. The module forms a software defined radio (SDR) solution when paired with an NI FlexRIO FPGA module for real-time, userdesigned processing. Through triggering mechanisms provided by the PXI platform, users can synchronize eight or more transceivers for MIMO and beamforming configurations. The module comes with FPGA digital signal processing (DSP) libraries and example architectures for common signal processing applications.

PXI Card

AIM’s (Trevose, PA) new PXI card model ACX3910-3U-1-EN is the latest addition to the extensive family of PXI cards for avionics databus test and simulation, providing off-the-shelf solutions for any test benches and test systems designed using PXI. Based on the field proven ACX3910-3U-1 STANAG3910 module for the Eurofighter Typhoon aircraft, the ACX3910-3U-1-EN provides all the same powerful functions and features but has an electrical front end and a specific firmware load to support the Rafale project.
